Systems and methods for automating the application of friction-modifying coatings

An assembly comprising:

• a mobile platform configured for being coupled to a vehicle;
• a binder applicator defining a plurality of openings linearly arranged into two rows extending substantially along the length of the binder applicator, the binder applicator being mounted on the mobile platform and coupled to a container of resin;
• an applicator apron attached to the binder applicator proximate to the plurality of openings;
• an air knife bar mounted on the mobile platform and coupled to an air compressor for generating compressed air, the air knife bar including a tube defining a slit in the tube extending substantially along the length of the tube and through which the compressed air is ejected;
• and
• an aggregate dispenser bar including at least one aggregate dispenser coupled to an aggregate bin and mounted on the mobile platform for dispensing aggregate via an extension and retraction assembly configured to extend and retract the binder applicator, the air knife bar and the aggregate dispenser bar.
